How to upgrade to latest stable nginx on Ubuntu 18

I have a linode server with virtualmin that hosts several of my domains. I am trying to find a guide on how to upgrade to latest stable nginx on Ubuntu 18 but the only article i found in medium said as a first step to Install the dependencies

$ sudo apt-get install software-properties-common python-software-properties

BUT a get a message

$ sudo apt-get install software-properties-common python-software-properties
sh: 1: $: not found
$ apt-get install software-properties-common python-software-properties
sh: 1: $: not found

The rest of the guide sugest the following but i am not surewhat to do since the first step is not working

Add the repository for the stable version of Nginx

$ sudo add-apt-repository ppa:nginx/stable

Now update it

$ sudo apt-get update

Run install

$ sudo apt-get install nginx
When it asks you if you want to keep using the old config or get the new config like this.
Configuration file '/etc/nginx/nginx.conf' ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation The default action is to keep your current version.
*** nginx.conf (Y/I/N/O/D/Z) [default=N] ?
Select N(No). It will Install the new version of the current config files in /etc/nginx/sites-available directory.

I'm not sure where you are getting your instructions from but the first step you are failing at is not part of the official instructions posted at

$ sudo wget
$ sudo apt-key add nginx_signing.key
$ sudo vi /etc/apt/sources.list deb bionic nginx deb-src bionic nginx
$ sudo apt-get remove nginx-common
$ sudo apt-get update
$ sudo apt-get install nginx
